摘要：PURPOSE: To suppress slipping out of a light guide plate from a frame and integrate the light guide plate with the frame. CONSTITUTION: This surface light source device 1 houses the light guide plate 4 and a fluorescent lamp 11 arranged so as to face a light incoming surface 10 of the light guiding plate 4 within the frame 2, houses light controlling members 7-9 arranged so as to face a light outgoing surface 17 of the light guide plate 4, and emits light emitted from the fluorescent lamp 11 in a surface shape through the light guide plate 4 and the light controlling members 7-9. A pair of claws 18, 18 engaging with the light outgoing surface 17 of both corner parts 24, 24 on the other side surface 16 of the light guide plate 4 is formed in the frame 2. Cut-out parts 30, 30 avoiding interference with a pair of claws 18, 18 of the frame 2 are formed in the light controlling members 7-9.
